This work describes the synthesis and characterization of a series of iminophosphorane-substituted phosphenium cations of the type [R2NPNP(Cl)2NPNR′2][GaCl4] [R = iPr; R′ = iPr (7[GaCl4]), SiMe3 (8)], which are directly derived from azidophosphenium salt [iPrNPN3][GaCl4] (2iPr[GaCl4]) and the corresponding chlorophosphane R2NPCl2. The reactivity of 7[GaCl4] toward 2,3-dimethylbutadiene (dmb) and 2
这项工作描述了一系列的类型的膦亚胺-取代phosphenium阳离子的合成和表征[R 2 NPNP(CL)2 NPNR' 2 ] [的GaCl 4 ] [R =我镨; R'= i Pr(7 [GaCl 4 ],SiMe 3(8)],它们直接从叠氮phosph盐[ i PrNPN 3 ] [GaCl 4 ](2 i Pr [GaCl 4 ])和相应的氯膦R衍生而来2 NPCl 2。7 [GaCl的反应活性4 ]向2,3-二甲基(DMB)和2,2'-联吡啶(联吡啶)进行了研究,导致形成的7-DMB [的GaCl 4 ]和7-CL。另外,详细研究了[(Me 3 Si) 2 NPN 3 ] [GaCl 4 ]( 2SiMe 3 [GaCl 4 ])的自缩合,以及[(Me 3 Si) 2 NPNP(XY)N(SiMe 3)) 2 ] [GaCl 4 ] [X = Cl; Y = Cl( 13),N 3(
